The laundry list of offenses includes everything money laundering
for Mexican drug cartels to ignoring U.S. regulations meant to
prevent dollars from reaching our country's known enemies.

Enemies like Al Qaeda.

One of the most damning parts of the report details HSBC's
relationship with Saudi based Al Rajhi Bank, a member of Osama
bin Ladin's 'Golden Chain' of important Al Qaeda financiers. The
relationship has spanned decades, perhaps that is why even when
HSBC's own internal compliance offices asked that it be
terminated in 2005, even when the US government discovered hard
evidence of Al Rajhi's relationship with terrorism, HSBC continued to business with the bank until
2010.

Al Rajhi bank is owned by the billionaire Al Rajhi family and
holds $59 billion in assets. It is Saudi Arabia's largest private
bank.

Al Rajhi's links to terrorism were confirmed in 2002 when
U.S. agents searched the offices of a Saudi non-profit and U.S.
designated terrorist organization, Benevolence International
Foundation (page 193). In that raid, agents uncovered a CD-ROM
listing the names of financiers in Osama bin Ladin's elite
'Golden Chain.' One of those names was Sulaiman bin Abdul Aziz Al
Rajhi, a founder of Al Rajhi bank.

From the report (page 194):

It doesn't stop there: Al Rahji is also known for
financial services to 9/11 hijacker Abdulaziz al Omari, who was
on American Airlines flight 11 (page
201).

An excerpt of a civil lawsuit against the bank from the Senate
report (page 201):

It wasn't until 2005 when the bank was linked to $130,000 worth
of U.S. travelers cheques cashed to support violent extremists in
Chechnya that HSBC's internal compliance office asked that the
bank discontinue all business with Al Rajhi (page 188). Some
employees listened, some did not.

By the end of 2006 the relationship was completely reinstated and
HSBC continued to provide the bank with U.S. dollars.
